    What size (CFM) remote kitchen exhaust fan should I use to properly vent a 4- burner gas cooktop? The distance from the exhaust above the stove to fan on the outside wall is 14 feet and there are 3 x 90 degree bends to get to the outer wall to vent.

    Does an induction cooktop require less CFM venting?
